eight characters. This method, like four-column fortune telling, is said to be able to determine a person's good fortune, bad fortune, ups and downs of honor and disgrace, with high accuracy. This calculation method is to determine the weight according to the year of birth of a person; The birth month determines the weight by month; The weight is determined by the number of days on the birthday. The year, month, day and hour of a person's birth are fixed, and the weight of the year, month, day and hour is specified. As long as the weight of the year, month, day and hour is added together, the fate of this person's life can be determined according to the "bone-singing song". The eight-character bone weight is divided by four or two (including four or two). Legend has it that people who are light-skinned in eight characters are easy to see unclean things and are easy to bump into evil spirits. Eight-character bones are too heavy to be disturbed by evil things, and of course it is not easy to succeed in playing the game of evocation. Obviously, it is not absolute that the heavier the eight characters, the better, and the lighter ones are better. Generally speaking, the eight-character heavy ones generally get better instructions than the light ones. The so-called general meaning means that what is good here may not be good in the eyes of some people.
